The invention provides a battery pack heat management device, a battery pack and a vehicle, and relates to the technical field of batteries. The battery pack heat management device comprises a shell, the shell comprises at least two heat management plates and a frame, one of the at least two heat management plates is located at the top end of the frame and connected with the frame, and the other heat management plate is located at the bottom end of the frame and connected with the frame. The inner wall of the frame and the heat management plates at the two ends of the frame define a containing cavity, the containing cavity is used for containing a battery cell, and the heat management plates at the two ends of the frame are attached to the two ends of the battery cell respectively. Each heat management plate is internally provided with a flow channel, and the heat management plates enable the battery cells to be cooled or heated through media in the flow channels. According to the technical scheme, the two heat management plates are attached to the top end and the bottom end of the battery cell respectively, the flow channels are formed in the heat management plates, the battery cell is cooled or heated through media in the flow channels, the flow channels do not occupy the area of the battery cell, the battery capacity of the battery pack is improved, joints do not need to be arranged between water pipes, and the risk of medium leakage is reduced.
本申请提供一种电池包热管理装置、电池包和车辆,涉及电池技术领域。电池包热管理装置包括壳体,壳体包括至少两个热管理板和边框,至少两个热管理板的其中一个位于边框的顶端、且与边框相连,另一个位于边框的底端、且与边框相连。边框的内壁与位于边框两端的热管理板围成容纳腔,容纳腔用于容置电芯,且位于边框两端的热管理板分别与电芯的两端贴合。每个热管理板内具有流道,热管理板通过流道内的介质使电芯降温或升温。上述技术方案通过两个热管理板分别贴合在电芯的顶端和底端,且热管理板内具有流道,通过流道内介质使电芯降温或升温,流道不占用电芯区域,提高了电池包电池容量,无需在水管之间设置接头,减少了介质泄露的风险。
